BOTTLE.

Patented Oct. 10, 1905.

Application tiled April 28,1905. Serial No. 257,868.

l of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine. Y

Generally speaking, this invention is an improvement in siphon-bottles, but to be ,more specific it consists in devices whereby the bottle can be readily refilled through the agency o'll such attachments as shown in my former application, Serial No. 242,666, bearing date of January 25, 1905.

The several parts are absolutely automatic in their operation, opening the moment suitable pressure is directed from the attachment and closing the moment the pressure is removed in the act ol withdrawing the' bottle.

The device is adapted to be used in conjunction with any form of siphon-head, as the rel'illing occurs through a secondary pipe. as shown in my former applications for patents, Serial Nos. 209,766 and 220,07, and bearing dates of May 25, 190A, and August IS, 1904, respectively, and not through the spout.

Other objects and advantages of the invention will appear in the following specilication, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings hereunto annexed and constituting a part of this specification, Figure l is a side. elevation and partial section ot' a siphon-head, showing the relative position of my invention. Fig. 2 is a section ofV the device positioned on the ordinary form of siphon-head. Fig. 3 is a perspective view of the spring-pressed valve employed.

I will now explain the construction of the several parts of my invention and subsequent-ly describe the operation of the same, reference being had to the above views by letter.

The main body ol the siphon-head is formed in the usual manner with the Siphontube A, spout B, spring-pressed valve C, and metal collar D, the latter for binding the head to the neck of. the bottle E. Formed integral with the Siphon-head and leading to the interior oi' the si hon-tube A is the secondary pipe F, which is formed with exterior threads and the interior seat f Adapted to engage with the exterior threads on the secondary pipe .F is the cap G, which is contracted in diameter to 'form the hollow nipple g. Within this cap G and resting against the rim of the secondary pipe F is tIie yielding washer H. Arranged to slide snugly within the hollow nipple g is the hollow stein yi of the valve I, the riin of the enlarged head fi of which engages with the inner face of the yielding washer H. This riin of the head i is formed with a groove `from which lead the passages a to the interior of the hollowstein fi. Interposed between the head fi and the seat f is the compression-spring J, which encircles a contracted llange on the head 'i'. This spring evidently causes a normal close seal between the rim of the head e" and the washer H.

N ow from the description so vfar gone into it is evident that, assuming that soda or other liquid can [low from the nozzle K under suitable pressure, by `forcing the stem i against the nozzle K the former will yield until the head t" leaves the washer H, when the soda is liree to pass through the hollow stem fi, passages a., secondary pipe F, and I'inally through the siphon-tube A to the interior of the bottle. By simply withdrawing the cap G from the nozzle K the spring J will immediately force the head t" against the washer H, and thereby prevent the backflow of the soda from the bottle.

As a means for clamping the bottle to the attachment from which the soda is received I have provided the projecting flange M on the outer periphery of the cap G, thereby affording a suitable projection to engage with any suitable lever or clamp on the attachinent.

From the above description it is manifest that the bottle can be readily and quickly refilled and detached 'from the stationary supply attachment, or in case it is desired to use the bottle as a stationary 'fixture it can be clamped to the attachment and supported on a neat stationary support and the soda continuously drawn and the bottle simultaneously refilled. This automatically-operated valve situated in the secondary pipe does not in the least hinder the free operation of the valve which controls the vflow of the soda through the ordinary spout, and

IOO

this fact makes my present invention appli-V .proportion of parts herein shown and described.

What I claim as my invention isl. In combination with a Siphon tube and spout, a secondary pipe leading to said tube and through which the Siphon-bottle is filled, a spring-pressed valve in said secondary pipe and arranged to automatically operate to prevent the esca e of the contents of the bottle substantia y as set forth.

2. In combination with a siphon tube and spout, a secondary pipe leading to said tube and through Which the Siphon-bottle is filled,

a spring-pressed valve arranged to close the passage through said pipe, a ni ple on said valve, said valve being arrange to Q en as pressure is directed against said nipp e and automatically close as said pressure is Withdrawn for the purpose set forth.

3. In combination With a siphon tube and spout, a secondary pipe leading to said tube and through Which the si hon-bottle is filled, a screw-ca engaging sai pipe, and a springressed vaIve arranged to control the flow of iquid through said pipe for the purpose set forth.

In testimony whereof I have hereunto signed my name to this specification in pres- 3 ence of two subscribing Witnesses.
